Abstract

BACKGROUND

Anti-Müllerian hormone (AMH) levels are used to evaluate the ovarian reserve. AMH serum concentrations have recently been studied among women attending fertility centers, and among women with regular menstrual cycles but normative values have not been established among fertile women: the objective of this study was to establish those values.

METHODS

This prospective cross-sectional study included 340 healthy fertile women attending a single centre, aged between 15 and 50 years. The women were all in the first trimester of pregnancy, had no serious medical history and attended the abortion service of the University Hospital of Nice, France. Serum AMH was measured using a second-generation AMH enzyme-linked immunosorbent assay.

RESULTS

Median AMH concentration was 2.42 ng/ml (25–75 percentiles 1.19–4.12). The relationship between AMH concentration and age was best fitted by a polynomial function. Serum AMH values rose until age 29 years and then showed a significant decline (R2= 0.289, P < 0.001). Normative values for serum AMH were established in different age groups between 15 and 50 years.

CONCLUSIONS

We established the normative values for serum AMH in a population of French fertile women in their first trimester of pregnancy.
